+Cross-compiling the GRUB
+========================
+
+GRUB defines 3 platforms:
+
+  - "Build" is the one which build systems runs on.
+  - "Host" is where you execute GRUB utils.
+  - "Target" is where GRUB itself runs.
+
+For grub-emu host and target must be the same but may differ from build.
+
+If build and host are different make check isn't available.
+
+If build and host are different man pages are not generated.
+
+As an example imagine you have a build system running on FreeBSD on sparc
+which prepares packages for developpers running amd64 GNU/Linux laptop and
+they need to make images for ARM board running U-boot. In this case:
+
+build=sparc64-freebsd
+host=amd64-linux-gnu
+target=arm-uboot
+
+For this example the configure line might look like (more details below)
+(some options are optional and included here for completeness but some rarely
+used options are omited):
+
+./configure BUILD_CC=gcc BUILD_FREETYPE=freetype-config --host=amd64-linux-gnu
+CC=amd64-linux-gnu-gcc CFLAGS="-g -O2" FREETYPE=amd64-linux-gnu-freetype-config
+--target=arm --with-platform=uboot TARGET_CC=arm-elf-gcc
+TARGET_CFLAGS="-Os -march=armv6" TARGET_CCASFLAGS="-march=armv6"
+TARGET_OBJCOPY="arm-elf-objcopy" TARGET_STRIP="arm-elf-strip"
+TARGET_NM=arm-elf-nm TARGET_RANLIB=arm-elf-ranlib LEX=gflex
+
+You need to use following options to specify tools and platforms. For minimum
+version look at prerequisites. All tools not mentioned in this section under
+corresponding platform are not needed for the platform in question.
+
+  - For build
+    1. BUILD_CC= to gcc able to compile for build. This is used, for
+       example, to compile build-gentrigtables which is then run to
+       generate sin and cos tables.
+    2. BUILD_CFLAGS= for C options for build.
+    3. BUILD_CPPFLAGS= for C preprocessor options for build.
+    4. BUILD_FREETYPE= for freetype-config for build (optional).
+
+  - For host
+    1. --host= to autoconf name of host.
+    2. CC= for gcc able to compile for host
+    3. CFLAGS= for C options for host.
+    4. CPPFLAGS= for C preprocessor options for host.
+    5. LDFLAGS= for linker options for host.
+    6. FREETYPE= for freetype-config for host (optional).
+    7. Libdevmapper if any must be in standard linker folders (-ldevmapper) (optional).
+    8. Libfuse if any must be in standard linker folders (-lfuse) (optional).
+    9. Libzfs if any must be in standard linker folders (-lzfs) (optional).
+    10. Liblzma if any must be in standard linker folders (-llzma) (optional).
+
+  - For target
+    1. --target= to autoconf cpu name of target.
+    2. --with-platform to choose firmware.
+    3. TARGET_CC= for gcc able to compile for target
+    4. TARGET_CFLAGS= for C options for target.
+    5. TARGET_CPPFLAGS= for C preprocessor options for target.
+    6. TARGET_CCASFLAGS= for assembler options for target.
+    7. TARGET_LDFLAGS= for linker options for target.
+    8. TARGET_OBJCOPY= for objcopy for target.
+    9. TARGET_STRIP= for strip for target.
+    10. TARGET_NM= for nm for target.
+    11. TARGET_RANLIB= for ranlib for target.
+
+  - Additionally for emu, for host and target.
+    1. SDL is looked for in stadard linker directories (-lSDL) (optional)
+    2. libpciaccess is looked for in stadard linker directories (-lpciaccess) (optional)
+    3. libusb is looked for in stadard linker directories (-lusb) (optional)
+
+  - Platform-agnostic tools and data.
+    1. make is the tool you execute after ./configure.
+    2. Bison is specified in YACC= variable
+    3. Flex is specified in LEX= variable
+    4. GNU unifont and Djvu sans are looked for in standard directories.

+New in 2.00:
+
+* Appearance:
+  * Official theme for gfxmenu (starfield)
+  * Menu is organised with submenus.
+  * Better default video mode selection using EDID.
+
+* New platforms:
+  * Itanium port.
+  * Fuloong2F support (including GRUB as firmware)
+  * Fuloong2E support (except GRUB as firmware)
+  * ARCS (SGI machines) port.
+  * qemu -M mips port.
+
+* grub-mount to mount filesystems using GRUB FS drivers and FUSE.
+
+* Changed security default so entries are locked by default if any superuser is
+  defined. 
+
+* New drivers:
+  * EHCI.
+  * AHCI.
+  * ESCC serial.
+  * IEEE1275 serial.
+  * EFI serial.
+  * Network stack for BIOS, IEEE1275, EMU and EFI, including TFTP, HTTP and DNS.
+  * VBE on coreboot support.
+
+* New filesystem, filters and disks formats:
+  * DVH partition map.
+  * Plan9 partition map.
+  * Big-endian mdraid.
+  * Big-endian cpio.
+  * ODC and NEWC cpio.
+  * ExFAT.
+  * Minix3fs.
+  * Big-endian minixfs.
+  * RomFS.
+  * Squash4.
+  * Support non-512B disk blocks.
+  * LUKS and GELI support.
+  * LDM read support (no install yet).
+  * LZOP.
+
+* Improved filesystem and disks formats support:
+  * HFS+ label support.
+  * Improved reiserfs support.
+  * multidevice, mirrored and raidz(2,3) ZFS support.
+  * RAID LVM (internal RAIDing) support.
+  * ZFS crypto support.
+  * ZLE and GZIP on ZFS support.
+  * Support ZFS up to 33.
+  * HFS string is now treated like mac-roman and not UTF-8
+  * HFS mtime support.
+  * Improved AFFS and SFS support.
+  * LZO-compressed btrfs support.
+  * cpio and tar symlinks support.
+  * Better FS detection to reduce false positives.
+
+* New boot protocols:
+  * Ability to load another coreboot payload when on coreboot.
+  * Plan9.
+  * Freedos.
+  * Ntldr/bootmgr (to load Windows bootloader).
+  * chainloader --bpb support to patch FAT or NTFS BPB in memory to correct
+    wrong partition offset.
+  * PXE chainloading support.
+  * Darwin 11 (Mac OS X Lion) protocol support.
+
+* Boot protocol improvements:
+  * Multiple initrd support.
+  * Basic illumos and xnu autoconfig.
+
+* Testing and debugging:
+  * New grub-fstest commands: cat, zfsinfo, testload xnu_uuid
+  * grub-fstest recursive directory compare for quickly checking that
+    a directory is read correctly.
+  * Backtace on crash (if gdb module is loaded, x86 only)
+  * Disk cache statistics gathering.
+  * GDB stub and GDB support script.
+  * "make check" and "make bootcheck" expanded to almost all platforms
+    (except i386-ieee1275, mips-arc, sparc64-ieee1275, ia64-efi and emu)
+  * New `time' command.
+
+* Performance:
+  * Lazy scanning to avoid accessing devices which aren't really used.
+    This avoids boot delay due to slow device scanning.
+  * Use CPU cache when accessing video memory.
+  * Search hints to first try the most likely device when searching for a
+    device with given UUID. This avoids slow scanning in most cases.
+
+* Internationalisation:
+  * Updated to Unicode 6.0.
+  * $"..." syntax for translation in grub scripting language. This allows easy
+    translation of grub.cfg at runtime.
+  * Translations to many languages included in official distribution.
+
+* Scripting:
+  * $grub_cpu and $grub_platform variables for conditioning grub.cfg on platform
+    at runtime.
+  * $feature_* variables to condition scripts on available features.
+  * Use of ids to identify menu entries.
+  * all_video module which is empty but depends on all video modules thus
+    allowing easy loading of all of them.
+
+* Installation:
+  * grub-mknetdir script for easy creation of netbootable GRUB directory.
+  * Itanium and mips support in grub-mkrescue.
+  * grub-install support for all platforms except emu.
+  * PreP partition install support.
+  * No files conflict between flavours (except grub-mkrescue for ppc). This
+    allows easy install of GRUB for several platforms.
+  * grub-mkstandalone script for easy creating of image including all modules
+    for platforms with generous limit on image size.
+  * program-transform-name now functions according to usual conventions.
+    Use --grubdir and --bootdir to get old behaviour.
+
+* ADLER32 and CRC64 support (for XZ and hashsum).
+
+* ofconsole renamed to console
+
+* Experimental support for compiling with Apple toolchain.
+
+* grub-mkdevicemap removed. Now all devices are detected on invocation of
+  any grub utility.
+
 New in 1.99:

 * Keyboard layouts support.

+@node Porting
+@chapter Porting
+
+GRUB2 is designed to be easily portable accross platforms. But because of the
+nature of bootloader every new port must be done separately. Here is how I did
+MIPS (loongson and ARC) and Xen ports. Note than this is more of suggestions,
+not absolute truth.
+
+First of all grab any architecture specifications you can find in public
+(please avoid NDA).
+
+First stage is ``Hello world''. I've done it outside of GRUB for simplicity.
+Your task is to have a small program which is loadable as bootloader and
+clearly shows its presence to you. If you have easily accessible console
+you can just print a message. If you have a mapped framebuffer you know address
+of, you can draw a square. If you have a debug facility, just hanging without
+crashing might be enough. For the first stage you can choose to load the
+bootloader across the network since format for network image is often easier
+than for local boot and it skips the need of small intermediary stages and
+nvram handling. Additionally you can often have a good idea of the needed
+format by running ``file'' on any netbootable executable for given platform.
+
+This program should probably have 2 parts: an assembler and C one. Assembler one
+handles BSS cleaning and other needed setup (on some platforms you may need
+to switch modes or copy the executable to its definitive position). So your code
+may look like (x86 assembly for illustration purposes)
+
+@example
+        .globl _start
+_start:
+	movl	$_bss_start, %edi
+	movl	$_end, %ecx
+	subl	%edi, %ecx
+	xorl	%eax, %eax
+	cld
+	rep
+	stosb
+        call main
+@end example
+
+@example
+
+static const char msg[] = "Hello, world";
+
+void
+putchar (int c)
+@{
+  ...
+@}
+
+void
+main (void)
+@{
+  const char *ptr = msg;
+  while (*ptr)
+    putchar (*ptr++);
+  while (1);
+@}
+@end example
+
+Sometimes you need a third file: assembly stubs for ABI-compatibility.
+
+Once this file is functional it's time to move it into GRUB2. The startup
+assembly file goes to grub-core/kern/$cpu/$platform/startup.S. You should also
+include grub/symbol.h and replace call to entry point with call to
+EXT_C(grub_main). The C file goes to grub-core/kern/$cpu/$platform/init.c
+and its entry point is renamed to void grub_machine_init (void). Keep final
+infinite loop for now. Stubs file if any goes to
+grub-core/kern/$cpu/$platform/callwrap.S. Sometimes either $cpu or $platform
+is dropped if file is used on several cpus respectivelyplatforms.
+Check those locations if they already have what you're looking for.
+
+Then modify in configure.ac the following parts:
+
+CPU names:
+
+@example
+case "$target_cpu" in
+  i[[3456]]86)	target_cpu=i386 ;;
+  amd64)	target_cpu=x86_64 ;;
+  sparc)	target_cpu=sparc64 ;;
+  s390x)	target_cpu=s390 ;;
+  ...
+esac
+@end example
+
+Sometimes CPU have additional architecture names which don't influence booting.
+You might want to have some canonical name to avoid having bunch of identical
+platforms with different names.
+
+NOTE: it doesn't influence compile optimisations which depend solely on
+chosen compiler and compile options.
+
+@example
+if test "x$with_platform" = x; then
+  case "$target_cpu"-"$target_vendor" in
+    i386-apple) platform=efi ;;
+    i386-*) platform=pc ;;
+    x86_64-apple) platform=efi ;;
+    x86_64-*) platform=pc ;;
+    powerpc-*) platform=ieee1275 ;;
+    ...
+  esac
+else
+  ...
+fi
+@end example
+
+This part deals with guessing the platform from CPU and vendor. Sometimes you
+need to use 32-bit mode for booting even if OS runs in 64-bit one. If so add
+your platform to:
+
+@example
+case "$target_cpu"-"$platform" in
+  x86_64-efi) ;;
+  x86_64-emu) ;;
+  x86_64-*) target_cpu=i386 ;;
+  powerpc64-ieee1275) target_cpu=powerpc ;;
+esac
+@end example
+
+Add your platform to the list of supported ones:
+
+@example
+case "$target_cpu"-"$platform" in
+  i386-efi) ;;
+  x86_64-efi) ;;
+  i386-pc) ;;
+  i386-multiboot) ;;
+  i386-coreboot) ;;
+  ...
+esac
+@end example
+
+If explicit -m32 or -m64 is needed add it to:
+
+@example
+case "$target_cpu" in
+  i386 | powerpc) target_m32=1 ;;
+  x86_64 | sparc64) target_m64=1 ;;
+esac
+@end example
+
+Finally you need to add a conditional to the following block:
+
+@example
+AM_CONDITIONAL([COND_mips_arc], [test x$target_cpu = xmips -a x$platform = xarc])
+AM_CONDITIONAL([COND_sparc64_ieee1275], [test x$target_cpu = xsparc64 -a x$platform = xieee1275])
+AM_CONDITIONAL([COND_powerpc_ieee1275], [test x$target_cpu = xpowerpc -a x$platform = xieee1275])
+@end example
+
+Next stop is gentpl.py. You need to add your platform to the list of supported
+ones (sorry that this list is duplicated):
+
+@example
+GRUB_PLATFORMS = [ "emu", "i386_pc", "i386_efi", "i386_qemu", "i386_coreboot",
+                   "i386_multiboot", "i386_ieee1275", "x86_64_efi",
+                   "mips_loongson", "sparc64_ieee1275",
+                   "powerpc_ieee1275", "mips_arc", "ia64_efi",
+                   "mips_qemu_mips", "s390_mainframe" ]
+@end example
+
+You may also want already to add new platform to one or several of available
+groups. In particular we always have a group for each CPU even when only
+one platform for given CPU is available.
+
+Then comes grub-core/Makefile.core.def. In the block ``kernel'' you'll need
+to define ldflags for your platform ($cpu_$platform_ldflags). You also need to
+declare startup asm file ($cpu_$platform_startup) as well as any other files
+(e.g. init.c and callwrap.S) (e.g. $cpu_$platform = kern/$cpu/$platform/init.c).
+At this stage you will also need to add dummy dl.c and cache.S with functions
+grub_err_t grub_arch_dl_check_header (void *ehdr), grub_err_t
+grub_arch_dl_relocate_symbols (grub_dl_t mod, void *ehdr) (dl.c) and
+void grub_arch_sync_caches (void *address, grub_size_t len) (cache.S). They
+won't be used for now.
+
+You will need to create directory include/$cpu/$platform and a file
+include/$cpu/types.h. The later folowing this template:
+
+@example
+#ifndef GRUB_TYPES_CPU_HEADER
+#define GRUB_TYPES_CPU_HEADER	1
+
+/* The size of void *.  */
+#define GRUB_TARGET_SIZEOF_VOID_P	4
+
+/* The size of long.  */
+#define GRUB_TARGET_SIZEOF_LONG		4
+
+/* mycpu is big-endian.  */
+#define GRUB_TARGET_WORDS_BIGENDIAN	1
+/* Alternatively: mycpu is little-endian.  */
+#undef GRUB_TARGET_WORDS_BIGENDIAN
+
+#endif /* ! GRUB_TYPES_CPU_HEADER */
+@end example
+
+You will also need to add a dummy file to datetime and setjmp modules to
+avoid any of it having no files. It can be just completely empty at this stage.
+
+You'll need to make grub-mkimage.c (util/grub_mkimage.c) aware of the needed
+format. For most commonly used formats like ELF, PE, aout or raw the support
+is already present and you'll need to make it follow the existant code paths
+for your platform adding adjustments if necessary. When done compile:
+
+@example
+./autogen.sh
+./configure --target=$cpu --with-platform=$platform TARGET_CC=.. OBJCOPY=... STRIP=...
+make > /dev/null
+@end example
+
+And create image
+
+@example
+./grub-mkimage -d grub-core -O $format_id -o test.img
+@end example
+
+And it's time to test your test.img.
+
+If it works next stage is to have heap, console and timer.
+
+To have the heap working you need to determine which regions are suitable for
+heap usage, allocate them from firmware and map (if applicable). Then call
+grub_mm_init_region (vois *start, grub_size_t s) for every of this region.
+As a shortcut for early port you can allocate right after _end or have
+a big static array for heap. If you do you'll probably need to come back to
+this later. As for output console you should distinguish between an array of
+text, terminfo or graphics-based console. Many of real-world examples don't
+fit perfectly into any of these categories but one of the models is easier
+to be used as base. In second and third case you should add your platform to 
+terminfokernel respectively videoinkernel group. A good example of array of
+text is i386-pc (kern/i386/pc/init.c and term/i386/pc/console.c).
+Of terminfo is ieee1275 (kern/ieee1275/init.c and term/ieee1275/console.c).
+Of video is loongson (kern/mips/loongson/init.c). Note that terminfo has
+to be inited in 2 stages: one before (to get at least rudimentary console
+as early as possible) and another after the heap (to get full-featured console).
+For the input there are string of keys, terminfo and direct hardware. For string
+of keys look at i386-pc (same files), for termino ieee1275 (same files) and for
+hardware loongson (kern/mips/loongson/init.c and term/at_keyboard.c).
+
+For the timer you'll need to call grub_install_get_time_ms (...) with as sole
+argument a function returning a grub_uint64_t of a number of milliseconds
+elapsed since arbitrary point in the past.
+
+Once these steps accomplished you can remove the inifinite loop and you should
+be able to get to the minimal console. Next step is to have module loading
+working. For this you'll need to fill kern/$cpu/dl.c and kern/$cpu/cache.S
+with real handling of relocations and respectively the real sync of I and D
+caches. Also you'll need to decide where in the image to store the modules.
+Usual way is to have it concatenated at the end. In this case you'll need to
+modify startup.S to copy modules out of bss to let's say ALIGN_UP (_end, 8)
+before cleaning out bss. You'll probably find useful to add total_module_size
+field to startup.S. In init.c you need to set grub_modbase to the address
+where modules can be found. You may need grub_modules_get_end () to avoid
+declaring the space occupied by modules as usable for heap. You can test modules
+with:
+
+@example
+./grub-mkimage -d grub-core -O $format_id -o test.img hello
+@end example
+
+and then running ``hello'' in the shell.
+
+Once this works, you should think of implementing disk access. Look around
+disk/ for examples.
+
+Then, very importantly, you probably need to implement the actual loader
+(examples available in loader/)
+
+Last step to have minimally usable port is to add support to grub-install to
+put GRUB in a place where firmware or platform will pick it up.
+
+Next steps are: filling datetime.c, setjmp.S, network (net/drivers),
+video (video/), halt (lib/), reboot (lib/).
+
+Please add your platform to Platform limitations and Supported kernels chapter
+in user documentation and mention any steps you skipped which result in reduced
+features or performance. Here is the quick checklist of features. Some of them
+are less important than others and skipping them is completely ok, just needs
+to be mentioned in user documentation.
+
+Checklist:
+@itemize
+@item Is heap big enough?
+@item Which charset is supported by console?
+@item Does platform have disk driver?
+@item Do you have network card support?
+@item Are you able to retrieve datetime (with date)?
